Suggestion: don't use root directory

Hi,

just found your nice plug-in and wanted to try it out. Thanks for publishing!

Noticed it crashes each time I access the characteristics from the Eve App. When changing the path in index.js to use /tmp/uptime.txt instead of /uptime.txt, it seems to work fine.

Now waiting for historic values to show up :)

Cheers,

Thanks for this plugin, great idea 👍
Same issue for me: Suddenly the temperature of another sensor appeared in the graph of the raspberry, and vice versa.
Cheers, Dani
